My new ride came with both, I understand the spica to be reliable and efficient, but can you eventually coax more ponies out of duals webbers? The ultimate goal of this car is a compromise between performance/steetability/reliability (that probably goes for everyone's car)
I am somewhat new to alfa's so any recommendations on books or advice is extremely welcomed. Just bought the car, so no big splurges yet, but it's a driving resto, and as everyone knows these Italian Girls like to spend money
